Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A318-112 airplanes, A319-111, -112, -115, -132, 
and -133 airplanes, A320-214, -232, and -233 airplanes, and A321-211, -
212, -213, -231, and -232 airplanes. This proposed AD was prompted by a 
quality control review on the final assembly line, which determined 
that aluminum alloy with inadequate heat treatment had been delivered 
and used on several structural parts. This proposed AD would require a 
one-time eddy current conductivity measurement of certain cabin, cargo 
compartment, and frame structural parts to determine if aluminum alloy 
with inadequate heat treatment was used, and replacement if necessary. 
We are proposing this AD to detect and replace structural parts made of 
aluminum alloy with inadequate heat treatment. This condition could 
result in reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by June 27, 2016.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0219, dated November 3, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A318-112 airplanes, A319-111, -112, -115, -132, and -133 airplanes, 
A320-214, -232, and -233 airplanes, and A321-211, -212, -213, -231, and 
-232 airplanes. The MCAI states:

    Following an Airbus quality control review on the final assembly 
line, it was discovered that aluminum alloy with inadequate heat 
treatment were delivered by a supplier for several structural parts. 
The results of the investigations highlighted that 1% of the stock 
could be impacted by this wrong material.
    Structural investigations demonstrated the capability to sustain 
the static limits loads, and sufficient fatigue life up to a certain 
inspection threshold.
    This condition, if not detected and corrected, could reduce the 
aeroplane structural integrity following fatigue load.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A320-53-1292, SB A320-53-1293, and SB A320-53-
1294 to provide inspection instructions.
    For the reasons described above, this [EASA] AD requires a one-
time Special Detailed Inspection (SDI) [i.e., eddy current 
conductivity measurement] of certain cabin, cargo compartment and 
frame parts [for material identification] and, depending on 
findings, replacement with serviceable parts.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
6431.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information:
     Airbus Service Bulletin A320-53-1292, dated July 23, 2015; 
including Appendices 01 and 02, dated July 23, 2015.
     Airbus Service Bulletin A320-53-1293, dated July 30, 2015; 
including Appendices 01 and 02, dated July 30, 2015.
     Airbus Service Bulletin A320-53-1294, dated July 23, 2015; 
including Appendices 01 and 02, dated July 23, 2015.
    The service information describes procedures for a one-time eddy 
current conductivity measurement of certain cabin, cargo compartment, 
and frame structural parts to determine if aluminum alloy with 
inadequate heat treatment was used, and replacement of any affected 
part with a serviceable part. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 46 airplanes of U.S. 
registry.
    We also estimate that it would take about 6 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $23,460, or $510 
per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
cost estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
